changing the ECC. This helps to see how the software handles the

At present this function does not accept a size for the FIT. This means
that it must be read from the FIT itself, introducing potential security
risk. Update the function to include a size parameter, which can be
invalid, in which case fit_check_format() calculates it.
For now no callers pass the size, but this can be updated later.
Also adjust the return value to an error code so that all the different
types of problems can be distinguished by the user.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

The 'sf' command is not supposed to rely on the MTD stack, but both
'sf' and 'nand' commands use helpers located in mtd_uboot.c. Despite
their location, these functions do not depend at all on the MTD
stack.
This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is
selected, which is inconsistent with the current situation. Solve this
by moving these three functions (which are only used by the above two
commands) out of mtd_uboot.c and put them in a C file only compiled
with cmd/sf.c and cmd/nand.c.

This declaration is not used anywhere in the whole tree. There is a
function 'mtd_id_parse()' which was renamed from 'id_parse()' in
commit 68d7d65100 ("Separate mtdparts command from jffs2"), but that
function is not used (anymore?) in cmd nand and build is fine without

If the value of either "nand options" or "bbt options" has a zero in
the most significant nibble, the '0x' prefix will be isolated from the
value like shown below:
|Device 0: nand0, sector size 128 KiB
| Page size 2048 b
| OOB size 64 b
| Erase size 131072 b

If we do nand device 0 command in u-boot on a device that has NAND support
enabled but no NAND chip, we can get data abort at least on omaps.
Fix the issue by replacing the check with nand_info[dev] as
suggested by Scott Wood. The check for name existed before because before
the array-to-pointer conversion there was no way to directly test
nand_info[dev] for emptiness.

Modern NANDs do not guarantee that data written in raw mode will not
contain bitflips just after writing them. This is fine since the number
of bitflips should be rather low and thus fixable by the ECC engine,
but since we are reading data in raw mode to verify if they match the
input data we cannot prevent failures if some bits are flipped.
The option of using standard mode to verify the data is not acceptable
either, since one of the usage of raw mode is to allow flashing images
that do not respect the standard NAND page layout or the default ECC
config (this is the case on Allwinner platforms, where the ROM code
tests several hardcoded configs, which are not necessarily matching the
NAND characteristics).
Add an extension to the nand write.raw command allowing one to disable
the verification step.

nand torture currently works on exactly one nand block which is specified
by giving the byteoffset to the beginning of the block.
Extend this by allowing for a second parameter specifying the byte size
to be tested.
e.g.
==> nand torture 1000000
NAND torture: device 0 offset 0x1000000 size 0x20000 (block size 0x20000)
Passed: 1, failed: 0
==> nand torture 1000000 40000
NAND torture: device 0 offset 0x1000000 size 0x40000 (block size 0x20000)
Passed: 2, failed: 0
